As someone who's played the game, I don't really see a point, it's basically a compressed version of the story.

If I hadn't played the game though this would be hella confusing at times, as things are often not properly explained, or fleshed out as well as in the game due to the anime's compressed nature. I would also find it very difficult to care for any of the characters, because while in the game you can spend hours of personal time with each one, here they are kinda just thrown in.

In conclusion I would only recommend it for those who want a very short, kinda footnote like version of the story of Persona 5.
